我怎样才能移动这个 Bootstrap 5 手风琴的箭头，使它们位于文本之前？

Question

所以这是来自 Bootstrap 5 web 页面的示例。 ( https://getbootstrap.com/docs/5.0/components/accordion/ ) 我的问题是，我怎样才能使箭头位于文本之前。 我尝试了不同的东西，但我无法让它工作。

<div class="accordion" id="accordionExample">
  <div class="accordion-item">
    <h2 class="accordion-header" id="headingOne">
      <button class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
        Accordion Item #1
      </button>
    </h2>
    <div id="collapseOne" class="accordion-collapse collapse show" aria-labelledby="headingOne" data-bs-parent="#accordionExample">
      <div class="accordion-body">
        <strong>This is the first item's accordion body.</strong> It is shown by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the <code>.accordion-body</code>, though the transition does limit overflow.
      </div>
    </div>
  </div>
  <div class="accordion-item">
    <h2 class="accordion-header" id="headingTwo">
      <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
        Accordion Item #2
      </button>
    </h2>
    <div id="collapseTwo" class="accordion-collapse collapse" aria-labelledby="headingTwo" data-bs-parent="#accordionExample">
      <div class="accordion-body">
        <strong>This is the second item's accordion body.</strong> It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the <code>.accordion-body</code>, though the transition does limit overflow.
      </div>
    </div>
  </div>
  <div class="accordion-item">
    <h2 class="accordion-header" id="headingThree">
      <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#collapseThree" aria-expanded="false" aria-controls="collapseThree">
        Accordion Item #3
      </button>
    </h2>
    <div id="collapseThree" class="accordion-collapse collapse" aria-labelledby="headingThree" data-bs-parent="#accordionExample">
      <div class="accordion-body">
        <strong>This is the third item's accordion body.</strong> It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the <code>.accordion-body</code>, though the transition does limit overflow.
      </div>
    </div>
  </div>
</div>

我尝试使用检查器的其中一件事是切换margin-right: auto; margin-left: auto; 我能够将它左对齐，但它仍然在文本之后。 这里是我修改的CSS

    .accordion-button::after {
    flex-shrink: 0;
    width: 1.25rem;
    height: 1.25rem;
    margin-right: auto;
    content: "";
    background-image: url(data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 16 16' fill='%23212529'%3e%3cpath fill-rule='evenodd' d='M1.646 4.646a.5.5 0 0 1 .708 0L8 10.293l5.646-5.647a.5.5 0 0 1 .708.708l-6 6a.5.5 0 0 1-.708 0l-6-6a.5.5 0 0 1 0-.708z'/%3e%3c/svg%3e);
    background-repeat: no-repeat;
    background-size: 1.25rem;
    transition: transform .2s ease-in-out;
}

Answer 1

这个问题有几个答案。 我刚刚尝试了这个 CSS 并且它有效：

 .accordion-button::before { flex-shrink: 0; width: 1.25rem; height: 1.25rem; margin-right: 1rem; content: ""; background-image: var(--bs-accordion-btn-active-icon); background-repeat: no-repeat; background-size: 1.25rem; transition: transform.2s ease-in-out; }.accordion-button::after { display: none;important; }

本质上我们正在做的是：

1. 制作一个新的 ::before 元素并将其样式设置为与引导程序默认设置相同
2. 隐藏内置的 bootstrap::after 元素。 我想你也可以使用类似 jquery 的东西来删除它
